I've got a Compaq Evo N400c Laptop computer which had a very small
amount of water leak into it (from wet hands) and since then, there is
no +5 to the hard drive to power up the drive. The machine works
otherwise, so I suspect just a fusable resistor blew, but I have not
had luck following the trace as it's a several-layer board and the
trace immediately disappears. Any chance anyone knows where that trace
runs, or has a schematic of this motherboard?

Thanks,
Eric Kotz
